Together with the connecting rod (17), the first pulley (18) also moves in the direction of the first beam (3). Since one end of the link belt (21) is fixed to the cantilever beam (5), the rear end corner portion (11) of the pedestal (10) is twice the moving distance of the first pulley (18). Lifts upwards.

When the rear end corner portion (11) is lifted to the tip of the cantilever beam (5), the wheel (X) outside the rear end corner portion (11) is guided by the guide rail on the upper surface of the cantilever beam (5). Since it rests on (4) and rolls, after that, the pedestal (10) moves along the cantilever (5).

When the first pulley (18) reaches near the base of the cantilever (5), the rear end corner (11) of the pedestal (10) approaches the first bracket (7), (10) Lifting to the upper stage is completed.

At this time, the first parallel link (8) and the second parallel link (12) are in an upright state, and the second bracket (9) is located on the uppermost part thereof.

While the pedestal (10) is being lifted or while being lowered, the pedestal (10) is kept horizontal by the parallel link mechanism (X 1).

That is, the line connecting the two connecting points of the first bracket (7) and the line connecting the two connecting points (a) and (b) of the second bracket (9) are always parallel to each other, and The line connecting the two connection points (c) and (d) of the bracket (9) and the line connecting the two connection points of the rear end corner (11) of the pedestal (10) are also kept parallel. These are due to the configuration of the first parallel link (8) and the second parallel link (12).

On the contrary, when lowering the pedestal (10) from the upper stage to the state of FIG. 1, the screw rod (13) is rotated in the reverse direction by the screw jack (14), and the connecting rod (17) and the first pulley are rotated. (18) is moved toward the second beam (6).

Since the link belt (21) is loosened, the weight of the pedestal (10) or the weight of the vehicle (27) when the vehicle (27) is placed causes the guide belt (4) to move downward along the guide rail (4). The wheel (X) rolls and descends, and the pedestal (10) descends along the cantilever (5).

When the wheel (X) passes the tip of the cantilever beam (5), the wheel (X) vertically descends due to gravity. It descends to the state of FIG. 1 and ends.
